The effect of resin concentration and electrodeposition bath temperature on the corrosion behaviour of polymer-coated steel
(Progress in Organic Coatings, 1990)
A.C. impedance measurements carried out on epoxy-resin electrocoated steels have been used to determine the pore resistance, capacitance and relative permittivity of the organic films. The time dependence of these ...
The determination of the corrosive behavior of polymer-coated steel with A.C. impedance measurements
(Pergamon-Elsevier Science Ltd, Oxford, 1990)
A.C. impedance measurements have quantitatively determined the pore resistance, capacitance and relative permittivity of organic films on epoxy-resin coated steels. The time dependence of these characteristics of protective ...
Behaviour of lipase immobilized on Amberlite IRA-410 / Ponašanje lipaze imobilisane na Amberlitu IRA-410
(Srpsko hemijsko društvo, 1990)
Two different lipases were immobilized on the strongly basic ion-exchange resin Amberlite IRA-410 in its Cl form and used to hydrolyse n-butylacetate. Opera¬tional stability and dependence of the rate on substrate concentration ...
Synthesis and spectroscopic study of some new N-natphthyl substituted 2-phenylacetamides
(Elsevier, Amsterdam, 1990)
In a continuation of our previous works the conformations of new N-(1,2,3,4-tetrahydro-1-napthyl and 1,2,3,4-tetrahydro-2-napthyl) substituted 2-phenylacetamides, PhCH2CONHR, were investigated by vibrational, 1H n.m.r. and ...
Electron‐ionization‐Induced fragmentation of N‐monosubstituted 2‐phenylacetamides
(Wiley, Hoboken, 1990)
Electron‐ionization‐induced mass spectra of N‐monosubstituted 2‐phenylacetamides were recorded and their fragmentation patterns were studied by metastable‐ion analyses. Representative deuterated analogues of these compounds ...
A kinetic study of the system phthalocyanine-copper(II) chloride-sulfuric acid
(Elsevier Science Sa, Lausanne, 1990)
In solutions of phthalocyanine, H2Pc, (c = 1-3 × 10-5 mol dm-3) and copper(II) chloride (c ≈ 10-3 mol dm-3) in sulfuric acid (c = 16-18 mol dm-3), two pseudo first-order reactions take place: (1) decomposition of H2Pc; (2) ...
A Kinetic Study of the System Phthalocyanine-Copper(II) Chloride-Sulfuric Acid
(Elsevier, 1990)
In solutions of phthalocyanine, H2Pc, (c = 1–3 × 10−5 mol dm−3) and copper(II) chloride (c ≈ 10−3 mol dm−3) in sulfuric acid (c = 16–18 mol dm−3), two pseudo first-order reactions take place: (1) decomposition of H2Pc; (2) ...
Synthesis and characterization of the CoSAPO- 14 and CoSAPO-34
(Butterworth Publishers, 1990)
The hydrothermal synthesis of CoSAPO-14 and CoSAPO-34 in the presence of isopropylamine as the template is described. CoSAPO-14 is a new MeSAPO material that predominantly forms at 125°C, whereas CoSAPO-34 is the main ...
Formation of AlPO4-15 and CoAPO-15 in the presence of hexamethylenetetramine
(Butterworth-Heinemann, 1990)
Two materials, AIPO4-15 and CoAPO-15, with the same aluminophosphate lattice have been obtained by hydrothermal synthesis in the presence of hexamethylenetetramine (HMTA). Their formation is attributed to the influence of ...
